Description

State of the art.

  The invention relates to a device for receiving at

  minus one transport roller between two profiled uprights

  preferably a roller accumulation conveyor, with a body which can be arranged at least partly in a

  groove of the profiled upright and with at least one recess available

  dried on the body, recess in which a

transport roller journal.

  Devices are already known which are used in particular for roller storage conveyors or the like and which have an L-shaped profile in sheet metal.

  steel with holes in which the transfer rollers

  port are mounted. The holes are arranged in the L-shaped profile fixedly with respect to each other with

  modular in size, so that the rollers can

  can be arranged relative to each other at a dis-

  predetermined tance. That way you can't choose

  the roller spacing freely, which limits the flexibility

  Lity of devices of this type having the shape of L-shaped profiles.

  In addition, a device is known which serves to receive

  see transport rollers by means of a grooved profile,

  the rollers can be arranged in a groove of the profile.

  This roller profile is made in the form of a sliding

  bucket and present at regular intervals with each other

  port to the others, holes in which one can insert and mount the axes of the transport rollers. When mounting a roller accumulation conveyor or the like with

  grooved profiles of this type, the profiled uprights are

  united to form a basic frame and the profiles are pressed into the groove of the profile upright. The transport rollers are inserted into the fixed base frame in such a way that

  we first thread an axis of the transport roller into a

  drilling of the grooved profile and then pressing the op axis

  installed transport roller, resiliently mounted by

  relative to the body of the roller, so that the transfer roller

  port can be placed substantially in a horizontal position, so that the elastically mounted axis can engage in the drilling of the grooved profile when the arrangement of the rollers

transport is in correct position.

  Devices of this type, serving to receive a transport roller, however have the disadvantage that they require time for their assembly and that a change or a disassembly cause considerable difficulties. In addition, the manufacture of a transport roller with at least

  an elastic mount axle is very expensive.

Advantages of the invention.

  The device according to the invention which is used to receive at least one transport roller is characterized in that

  the shaft of the transport roller can be inserted into a recess

  body previously assembled, open upwards, on the

profiled upright.

  Such a device according to the invention has a simple and economical configuration for receiving a transport roller intended for a roller accumulation conveyor or the like. Thanks to the prior fixing of the device on profiled uprights, it is possible, after having constructed the base frame with the profiled uprights, to obtain simple and rapid assembly of the transport rollers freely from the top, in a recess open upwards. In this case, it is not necessary to provide an elastic configuration of the axes on the transport rollers. In this way, a considerable reduction in manufacturing costs can be achieved not only due to the reduction in assembly time due to the good accessibility of the transport rollers, freely from the top, to the device, but also due to the configuration

simple transport rollers.

  According to an advantageous embodiment of

  the invention, the recess open upwards presents a sec-

  tion whose cross section is narrowing. Of this

  way, you can keep the transport roller in its posi-

  tion after having inserted it into the device in a simple way thanks to the snap-on connection formed in a removable manner and

  prevent it from lifting up.

  According to another advantageous configuration of

  the invention, part of the section, which will shrink

  sant, oriented towards the axis of rotation of the journal of the transport roller, corresponds substantially to the outside diameter of the journal. In this way it is possible in a simple way to obtain a good mounting and a good guiding of the journal of the transport roller in the recess. According to another advantageous configuration of the invention, provision has been made for the recess open upwards to be located in an external zone at the edge of the body. In this way, the section which is located between the recess and a front face of the body can be constituted in the form of an elastic branch. Thus, the section which becomes narrower, during the insertion of the transport roller, can be widened in the body and the elastic branch can be deployed outwards without any deformation of the section which occurs. shrinking. This way you can get an easy insertion. Thanks to the flexible elastic configuration of the branch, it returns to its starting position after the deployment and insertion of the transport roller, and

  may prevent the transport roller from lifting up again

calf, up.

  According to another advantageous configuration of

  the invention, a hole has been provided at the end of the oppo- body.

  seated in the recess, a hole in which an element can be inserted

  fixing. In this case, a square head nut and a countersunk head screw can be advantageously used as fixing elements which allow a connection to be made.

  simple by screwing with the profiled upright in the form of a groove.

  Thanks to this simple attachment, it is also possible to

  place the device where you want along the groove of the profile upright, whereby you can get a

  continuous spacing of the rollers relative to each other.

  According to another advantageous configuration of the invention, provision has been made for the body to have, on a side wall facing the grooved profile, a projection, the

  width corresponds substantially to the groove of the upright

  the. This, in the mounting position, engages in the

  groove and constitutes a rotation lock.

  According to other characteristics of the invention: - the projection arranged on a lateral face has a projection located on the opposite lateral face, projection which is made in width larger or smaller than the projection, - one provides on an upper face of the projections at least two bosses preferably having a conical shape, bosses which are constituted by an anterior edge of the projections,

  - the body presents, symmetrically with respect to its per-

  çage, a recess open upwards,

  - several bodies can be placed on a groove of the

  tants profiled, continuously, at a certain distance

one another.

  The invention will be described below in more detail on the basis of an embodiment shown in the accompanying drawings.

  Description of the exemplary embodiment.

  In Figure 2, there is shown schematically a roller storage conveyor 11 with a base frame

  12. This has vertical supports 13, 14, which are

  bare at a distance from one another by transverse uprights 16, 17. On the upper end zone of the supports 13, 14, profiled uprights 18, 19 which extend horizontally by means of known connection techniques have been fixed. compared to

  supports 13, 14. The profiled uprights 18, 19 have a sec-

  square cross section. On each side face 22, 23, 24, 26 and 27, 28, 29, 31 of the uprights 18 and 19, a groove 32, 33, 34, 36 and 37, 38, 39, 41 is provided. The grooves are are found on the transverse axes of the profiled uprights 18, 19. As an alternative to the profiled uprights 18, 19 shown in FIG. 1, other profiled uprights can also be provided using at least one groove 32, 37, oriented towards the supports

  13, 14 and a groove 33, 38 oriented towards a central plane along

  gitudinal 42 of the base frame 12, on the interior faces 43,

44 of the uprights 18, 19.

  After erecting the base frame 12 with the

  horizontal profile 18, 19 mounted above, devices can be mounted for receiving a transport roller 48 on the right profile upright and the left profile upright 18, 19, by means of fixing devices, in the groove 33, 38. The fixing device 49 consists of a square head nut 52 and a countersunk screw 53. Alternatively, other fixing devices can be provided which can fix the device to the profiled uprights 18, 19 in connection with the

groove 33, 38.

  Once the square head nut 52 has been threaded

  in the groove 33, the device 46 is placed on the inner face

  lower 43 of the profiled upright 18 at the location of the groove 33.

  The countersunk screw 43 passes through a bore 54 of the device.

  positive 46, so that a side face 57 of the device

  tif 46 rests on the lateral face 23 of the right-hand upright 18. An assembly of this type is apparent from the representation of the profiled upright 18. On the left is shown the device

46 in its state when mounted.

  The devices 46 can be installed with a template serving as an auxiliary means, on the right profiled upright and the left profiled upright 18, 19, so that an axis of rotation 71 of the transport roller rests at right angles

  compared to the uprights 18, 19 in the case of a trans-

  roller accumulation carrier 11.

  In addition, it is possible to determine with this template the spacings of the transport rollers 48 with respect to each other. Thanks to this template we can determine a dimension

  modular in a specific way per application and the avail-

  sitives 46 are fixed correspondingly on the profiled uprights 18, 19. Thanks to the advantageous embodiment of the fixing device 49, it is also possible after the fact to fine-tune the spacings, because the fixing device 49, constituted under the shape of a clamping device, can

  be placed anywhere in the longitudinal direction of the groove 33, 38.

  The transport roller 48 can be inserted freely from above after the respective positioning in a device.

  positive 46, on the inner side 43, 44 of the uprights 18, 19.

  In FIGS. 2 to 4, the device 46 is shown. It has a body 61 of substantially square shape, in which the bore 54 is disposed in a left border area 62. This bore 54 has a recess 63 on the face left side and on the right side face 57, 58, so that one obtains, by means of the countersunk screw 53, a centering of the body 61 relative to the square head nut 52

in groove 33.

  On a border area 64 opposite to the left border area 62, a recess 66 open upwards has been placed. This has a bearing 68 located in a longitudinal axis 67 of the body 61 and serving to receive a pin 69 of the transport roller 48 (FIG. 1). In this case, an axis of rotation 71 of the transport roller 48 is located on the axis

  longitudinal 67 of the body. Likewise, the center of the per-

  hole 54 in the longitudinal axis 67 of the body 61.

  The bearing 68 has a diameter which corresponds substantially to the diameter of the pin 69. Advantageously, a negative clearance has been provided during the production of the bearing, so that an engagement movement can be prevented

  friction of the journal 69 of the transport roller 48. The

  link 68 is open upwards and has a section 72 which narrows then widens again upwards and

  passes through a zone 73 which is constituted, with respect to the di-

  meter from bearing 68, at least as large. Advantageously, the zone 73 can widen further upwards, so that introductory chamfers 81 are formed, which make it possible to have more reception and arrangement.

  easy of the pin 69 in the device 46. Thanks to the sec-

  tion 72 which is shrinking, it is possible to fix the pin 69 arranged in the bearing 68 and prevent the lifting of the

  transport roller 48 upwards.

  Between the recess 66 and a front face 74, an elastically flexible zone 75 has been formed. When the transport roller 48 is inserted into the recess 66, this zone 75 provided with elastic lips can flare towards

  the outside so that the section 72 which goes in

  narrowing, can be widened during the insertion phase of the transport roller 48, and the pin 69 can be put in place in the bearing 68. Then, this zone 75 returns elastically to its starting position and blocks the pin 69

in bearing 68.

  On the lateral face 57 is arranged, in a sec-

  center 76 of the body 61, a projection 77 which has a shape

  rectangular. This projection 77 comes into engagement when the device

  sitive 46 is mounted in the groove 33 of the profiled upright 18 and serves to block the device 46 in rotation. The projection 77

  in this case forms the spring of a groove connection and res-

  comes out. This projection is adapted over its entire width to the large

deur of the groove.

  On the side face 58 opposite the side face

  57 a projection 78 has also been formed, the configuration of which

  tion corresponds to the projection 77. Unlike the projection 77, the projection 78 is formed with a greater width so that the latter constitutes for example a rotation lock for a groove of 10 mm, while the projection 77 can constitute a rotation block for an 8 mm groove. The protrusions 77, 78 may, in a manner specific to the use, have widths which deviate from the dimensions

mentioned above.

  Thanks to the projections 77, 78 which consist of

  different ways as to their width, we create a flexibility

  larger for the device 46 because it can be in-

  already bent in profiled uprights 18, 19 having two widths

of different grooves.

  On one face of the projections 77, 78, two bosses 82 are located in the area of the central section 76.

  a certain distance from each other. These bosses are

  sants of a front edge 83 of the projections 77, 78 towards the body 61, and have in cross section the shape of a cone. It can also be provided that the bosses 82 have sections

different cross-sections.

  The bosses 82 have the advantage that one can

  compensate for the play in the grooves of the profiled uprights 18, 19.

  In this way it can be ensured that the device 46 always rests on a lower edge of the groove 32, 33, 34, 36 and 37, 38, 39, 41 of the uprights 18, 19. This has the

  effect that all the axes of rotation 71 of the transfer rollers

  port 48 are on one level.

  The device 46 is advantageously produced in the form of an injected plastic part which advantageously has good sliding properties, so that it is possible to receive the

  transport rollers 48 with low friction in the pa-

  liers. As a variant, provision may also be made to use an aluminum casting or the like. This way we have

  a simple configuration of the device 46, without it being necessary to

  stop machining the faces.

  The individual fixing of the device 46 on the profiled uprights 18, 19 makes it possible to adjust continuously

  the interval between the transport rollers 48. In this way

  lesson, we can insert a device of this type, independently

  the diameter of the transport roller 48, for different trans-

  roller storage carriers 11. In addition, it is possible

  ble to have an easy disassembly of the transport roller thanks to the advantageous embodiment of the recess 66 on the

  device 46, transport roller which can be easily disassembled

  quickly and in the event of damage and replaced by a

replacement roller 48.

  An alternative configuration of the device 46 can consist in, for example, having a left recess and a right recess 66 symmetrically with respect to the

  drilling 54. In this way, it can be inserted by means of a

  positive 46, two transport rollers 48 at a predetermined distance

finished from each other.
